Android devices can successfully connect to the AP’s SSID and obtain valid IP addresses. However, iOS devices occasionally fail to connect properly and are assigned IP addresses in the 169.254.xx.xx range.


To address the issue of iOS devices not obtaining the relevant IP address when connecting to your Nebula WiFi network, please follow the provided troubleshooting steps:

  • Reset network settings on client: Remove (forget or delete) the SSID profile from the client's Wi-Fi list. Then, attempt to reconnect to the network.
  • DHCP issues: As you mentioned the iOS devices are getting a 169.254.x.x IP address - APIPA, this indicates a failure to obtain an IP address from the DHCP server. Please ensure your DHCP server is functioning correctly and has available IP addresses in the pool.
  • DNS Issues: Verify that the DNS servers assigned by DHCP are accessible and functioning correctly. You can try setting a public DNS server like on one of the affected iOS devices to see if it resolves the issue.
  • iOS version: Upgrade the iOS to the latest version

You can also utilize the WiFi Aid feature to help identify the issue with the iOS client:
